Floating Production Storage and Offloading (FPSO), a significant offshore oil-gas production system, faces a variety of risks in the process of operation. Vapor cloud explosion (VCE) caused by combustible gas leakage is likely to occur on the topside of FPSO. As an initial accident, VCE has an effect on surrounding devices, leading to subsequent consequences and ampliative scale of the accident. The process, known as the domino effect, can result in severe consequences, indicating that it is necessary to analyze characteristics and impacts of the domino effect on FPSO. In this study, the most risky equipment is determined. VCE overpressure on device surfaces caused by gas leakage of this most risky equipment is calculated, and the results are used for analyzing the domino effect based on Bayesian network.
